Micro-ATX or mATX boards are essentially a slimmed down version of the
standard ATX motherboard. They offer similar expansion features as
their full sized brethren including support for the same CPUs and
memory. Most of the mATX platforms that offer great performance have
been rare with the bulk of the blame aimed at the available chipsets.
With that said, the latest generation Intel X58 Chipset has proven to
be anything but lack luster and ASUS has married it with the mATX form
factor to produce something truly special.
